Field studies and laboratory experiments in large recirculating flume have established that resistance to flow and sediment transport in alluvial channels are related to form of bed roughness; forms of roughness can be divided into lower and upper regimes of flow on basis of their shape, resistance to flow, and sediment transport; possible relationship that may prove useful in predicting configuration of bed is introduced.
